Proper handling and care will extend the life and
service of the meter.
Turbine Rotor
The meter is virtually maintenance-free. How-
ever, it is important the rotor moves freely. Keep
the meter clean and free of contaminants.
The rotor can be removed for cleaning and inspec-
tion. Begin by unscrewing the nose cone from
the outlet end of the meter. A 1/4" square socket
extension can be used. Remove the lock and
flat thrust washers. Rotor can then be removed
from shaft. Note orientation because rotor is
not bi-directional. Remove debris or deposits
using soft brush or small probe. Reassemble in
reverse order.
Blowing compressed air through the turbine
assembly could damage the rotor.
Do not allow liquids to dry inside the turbine.
Handle the rotor carefully. Small scratches
or nicks can affect accuracy.
NOTE: Make sure the arrow on the turbine outlet
is pointed in the direction of fluid flow.
Battery Replacement
The computer display is powered by two 3-volt
lithium batteries which may be replaced while the
meter is installed. When batteries are removed or
lose power, the batch and cumula tive totals and
the field and factory calibrations are re tained.
(Battery) – Avoid mechanical or electrical
abuse. Batteries may explode or cause
burns, if disassembled, crushed or exposed
to fire or temperatures in excess of 212°F
(100°C). Do not short circuit or install with
incorrect polarity. DO NOT INCINERATE.

CAUTION
Batteries should ONLY be replaced with
P/N 113520-1 Kit (Includes two each P/N
902004-2 Batteries). Do not mix old with new.
Do not use other brands or technologies.
Open battery cells should be disposed
of in accordance with local regulations.
Lithium batteries are best disposed of as a
non-hazardous waste when fully or mostly
discharged. EPA does not list or exempt
Lithium as a hazardous waste. If waste
lithium batteries are still fully charged
or only partially discharged, they can be
considered a reactive hazardous waste
because of unconsumed lithium remaining
in the battery. Such batteries may qualify
as "Universal Waste" in many jurisdictions
within the U.S. and thus can be shipped for
disposal or recycling in accordance with
Universal Waste requirements.
If the display becomes dim, blank or the low
battery message appears (see below), replace
the batteries as follows:
1. Remove the four Phillips-head screws from
the face of the meter and lift the faceplate
from the turbine.
2. Remove the old batteries and clean any cor-
rosion from the terminals.
3. Install new batteries. Make sure the positive
post is in the correct position.
4. When the batteries are replaced, the faceplate
will power ON. Check the display to ensure
normal functions have resumed before as-
sembling again.
5. Reseat batteries, if necessary, and position
the faceplate on the turbine housing. To
avoid moisture damage, make sure the seal
is fully seated. Tighten the four screws on
the faceplate.
